So, I went to leave Detroit on Sunday after Son of SnoDrift, and in the process of checking my tire pressure, I noticed something was amiss! My front driver's side tire had a pretty significant blister on it. With 4200 miles on them. Not cool at all. That, and General does not have a road hazard warranty on them (despite the fact that this is obviously a manufacturing defect - there are absolutely no scratches, bruises, or even a tiny scrape on the sidewall) and there are no shops here who will warranty all four tires for me, since I need them all replaced at once.

I've got a road hazard warranty back at the shop I bought them from in Battle Creek... but I'm in Detroit. So I talked to the shop back in BC, and they said if I bought ONE tire here to replace the bad one, take the bad one with me back to them, they'd refund me for the one tire/mounting/balancing. Whether or not they'll replace all four tires is yet to be seen. I'm really not going to be thrilled if they decide that running one tire with a different circumference than the other three is a good idea on an AWD car...

I really like supporting local small mom & pop shops, but sometimes there's a benefit to getting stuff from big chains, especially when it comes to warranty work. Hopefully driving carefully home on slightly mismatched tires won't kill anything, right?

Those tires have 4200 miles on them? Jeebus, they look damn near bald.

You're fine for driving home on your bad tire (our cars come with donuts and they don't always match the tires size that we have installed), and if they will only replace the bad one, demand that they pay for a shop that can shave your new tire to the correct diameter.
